GEAR-GREASER.

Application filed March 29. 1&18.

7 '0 all whom. it may concern:

Be it known that I, .DANIEL E. Paves):- FUs, a citizen of the United States, residing at Dooley, in the county of Sheridan and State of Montana, have invented certain new and useful In'lprovements in Gear-(Jlreasers, of which the following is a specitieztion.

' This invention relates to lubrication, and more especially to force feed devices which are meclmnically operated; and the object of the same is to provide means for applylug a. fixed lubricant such as grease to the teeth of a very large gear such as some times constitutes the fly wheel in motor plants. A further object is to provide means for driving this greaser from the rotation of the gear itself, so that its lubricat ing action will cease when the gear stops rotating, and so that the amount of lubricant fed to the teeth of the gear will be dependent on the rotation and speed of rotation of the latter.

These several objects are carried out by constructing the device in a manner hereinafter more fully desm'ibedand claimed and as shown in the drawings. wherein:-

Figure 1 is a side elevation of the greaser complete, and

Fig. 2 a vertical section through the same and a portion of the gear being'lubricated, Fig. is an enlarged transverse section of the hollow pinion referred to below.

Fig. 4 is a side elevation partly broken away. showing a modified and in some cases a preferred form of this invention.

lVIountcd in a suitable bracket 1 is a horizontal pipe 2 having perforations 3 near one extremity and a piston head 4 fixed on its other extremity and threaded around its periphery as at 5. A hollow pinion 6 has its hubs 7 and 8 rotatably mounted on the pipe '2, and the last named hub may well be threaded as shown at the left in Fig. 2 and closed b a cap nut 9 which also closes this end of the pipe. The other hub 7 may have a packing land 10 as shown. but essentially it is provided with a single tooth 11. At each revolution of this hub, the said tooth engages one of the teeth of a gear 12 whose shaft 13 is journaled as at 14 in the bracket 1 and has at its remote. end a single tooth 15 engaging the long teeth 16 on a drum 17 which is to contain the lubricant.

This drum is internally threaded as shown at 18 to engage the threads 5 and the periph cry of the piston head 4. and it follows that Specification of Letters Patent.

Patented Dec. It), 1918.

Serial No. 225.557.

the rotation of the shaft 13 will intermittently cause the rotation of the drum and its advance toward the left. in Fig. "2. whereby lubricant or grease at the right of the piston head will be forced through the tube or pipe 2.

The pinion (S is preferably of about the constriurtion best seen in Fig. 3. Each of its teeth 20 is hollow and rather long on a line parallel with its hubs and its axis, and in one or both walls of each tooth are per forations 21 through which the lubricant exudes. This pinion rotates around the pipe 2 where the latter is perforated at 3 and the perforations come successively into register with the inner ends of the openings in the several teeth. lVhen now grease or other lubricant is forced along the pipe by the means already described. it oozes out the perforations 3 and is picked up by the hollow teeth' 20 as they pass said perforations. Eventually these teeth become filled with grease and the same is ejected through the perforations 21. The large gear designated by the letter G has its teeth in mesh with those ofthe pinion (3 as indicated in Fig. 1, and such pinion is rotated quit-e rapidly by the revolution of the gear. This rapid rotation is reduced by the means described, although I would not wish to be limited to this exact means. so that eventually the drum 1? is rotated in steps and very slowly. As has been explained the rotation ejects the grease therein along the pipe 2, and into the pinion t3. and the latter applies it to the teeth of the large gear G automatically. \Vhcn the rotation of this gear ceases. the action of the greaser ceases. and when the ro ation of the gear (1: is sped. tl action of the greascr increases automatically. The device needs no attention cxce 'iting that on rare oc asions the drum must be filled with grease to the rightof the piston head 4. and said head reset near the left end of the drum so that it may repeat the action described above.

f nch is the construction of that form of my invention shown in Sheet 1 of the drawings. On Sheet 2 is shown another and much similar (onstruction. The bracket 1 carries the pipe 2-perfn'attal at 23 within the hollow pinion (S which meshes with the large gear G, and journaled at H in said bracket is a shaft 13 having in the present instance a long tooth 15 meshing with the teeth in a ring is on the periphery of thefirum 17 the latter being internally threaded at 18 to engage the threads on the edge of the piston l as best seen in Fig. 2. The huh 7 of? the pinion 6 isheld on the pipe 2 by a gland l0, and this hub carries a gear 11 meshing through an idler 11. With a gear 12" loose on the shaft 18. Said idler is mounted on a pin 1 projecting from the bracket 1 and carry ing an upstanding stud 1 as seen. On this stud is mounted a pinion 3O meshing with a rim gear 31 fast on the shaft l3, and the large gear 12, carries a single tooth 32 which at each revolution of said gear turns the pinion 80 the distance of one tooth thereon. This turns the rim gear the distance of one tooth on its periphery, and at one con'iplete revolution of the shaft 13 the long tooth turns the toothed ring; 16 one tooth. Thus it will be seen that the relation between the large gear G and the rotation of the drum 1? is varied considerably by this arrangement and the gear could make a great many revolutions without the drum being moved forward more than fraction of an inch. This, however, is What is desired, because the forward feeding of the drum causes the lubricant to exude through the pipe and the perforations 3 thereof, and he delivered onto the teeth of the large gear in a manner already I 551i forth.

The foregoing description and the draw ings have reference to what may be considered the preferred, or approved forms oi my invention. t is to he understood that i. may make such changes in construction and arrangement and combination of parts, 1nd tcrials, dimensions, et cetera, as may prove expedient and fall Within the scope of the appended claims.
